AT04-08PB Equivalent & Substitute Parts

Part Overview

The AT04-08PB is an 8-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component serves as the female housing element in the AT Series™ connector family, designed for applications requiring crimp-terminated connections with free-hanging in-line mounting. The part is actively produced and maintains full compliance with RoHS3 and REACH regulations.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, while maintaining electrical and mechanical compatibility within the specified parameter constraints.

Substitute Part Grouping Explanation

Substitute parts for the AT04-08PB are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires that alternative parts maintain:

Critical Matching Parameters:

8-position configuration
Receptacle connector type
Male pin contact accommodation
2-row arrangement
Free-hanging in-line mounting capability
Crimp contact termination method
Latch holder fastening mechanism
Identical operating temperature range (-55°C ~ 125°C)

Regulatory Compliance:

RoHS3 compliance status
REACH unaffected classification
EAR99 export control designation

The DT04-08PB from TE Connectivity Deutsch Connectors satisfies all critical parameter requirements and maintains full regulatory compliance, establishing it as a direct functional equivalent.

Engineering Selection Recommendations

Both the AT04-08PB and DT04-08PB are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

Availability and Lead Time: The DT04-08PB currently maintains higher inventory levels (2064 units) compared to the AT04-08PB (902 units), which may influence procurement timelines.

Regulatory Compliance: Both parts meet identical regulatory requirements under RoHS3 and REACH frameworks, with EAR99 export classification. Either part is suitable for applications requiring compliance documentation.

Environmental Performance: The DT04-08PB includes IP68 and IP6K9K ratings, providing enhanced environmental sealing specifications beyond the base AT04-08PB requirements. Applications requiring these environmental protection levels should specify the DT04-08PB.

Thermal Performance: Both parts operate across the identical temperature range (-55°C ~ 125°C), ensuring thermal compatibility in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the DT04-08PB directly replace the AT04-08PB in existing assemblies?

A: Yes. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, connector type, contact configuration, mounting method, and termination type. The parts are functionally interchangeable within the specified operating parameters.

Q: Are there differences in insulation material between these parts?

A: The AT04-08PB specifies thermoplastic insulation material, while the DT04-08PB uses plastic insulation. Both materials are suitable for the operating temperature range and environmental conditions. Material selection should be evaluated based on specific application requirements.

Q: What does the "Contacts Not Included" note mean for both parts?

A: Both the AT04-08PB and DT04-08PB are housing components only. Contact pins must be sourced separately and are not included with the housing purchase. Ensure that selected contacts are compatible with the crimp termination method and 8-position configuration.

Q: Do both parts support the same mounting configuration?

A: Yes. Both parts are configured for free-hanging in-line mounting with latch holder fastening. Installation procedures and mounting clearance requirements are equivalent between the two parts.

Q: Are there any export restrictions on either part?

A: Both parts carry EAR99 classification, indicating they are not subject to specific export licensing requirements under U.S. export control regulations.

Q: What is the significance of the IP68 and IP6K9K ratings on the DT04-08PB?

A: These ratings indicate enhanced environmental protection. IP68 specifies protection against dust ingress and temporary immersion in water. IP6K9K specifies protection against high-pressure water jets. The AT04-08PB does not specify these ratings. Applications requiring these environmental protections should use the DT04-08PB.
